Sennheiser CX 80S
The Sennheiser wired earbuds receive mixed feedback. Many users praise the clear, balanced sound and excellent value for the low price, with some calling them the best wired earbuds under $20. However, several reviews note weak bass, durability concerns like one side dying after a year, and one user found the sound quality surprisingly poor for the brand. Overall, they are seen as a solid budget option with good clarity but not for bass lovers.
Pros
- Clear and balanced sound
- Excellent value for money
- Good clarity and detail
- Comfortable fit
- Lightweight design
Cons
- Weak bass response
- Durability concerns (one side dies)
- Thin cable
- Inconsistent sound quality across units
- Button control issues
